ARRANGEMENT OF SASI-I-FASTENERS.

Specification of Letters Patent No. 9,649, dated April 5, 1853.

To all fio/0m 15 may concern.'

Be it known that I, HENRY R. NoLL, of Lewisburg, Pennsylvania, havelnade certain new and useful Improvements in Sash- Fasteners, o f whichthe following is a description.

My invention and improvements consist in so arranging the spring catchfastenings for window sashes that the spring for the upper sash may becommanded without interference from the lower sash. That is to say, ifthe lower sash is raised, the spring of the upper sash can be managedwithout dropping the lower sash.

In Figure l, I have shown the rear side of the plate and springfastenings, in Fig. 5, the front side of the same, in Fig. 2 alongitudinal section, of the same, in Fig. 3 a transverse section, ofthe same, in Fig. 4 the plate let in to the window frame and also thespring roller in position. in Fig. 6 the notches in the window sash.

The two spring fastenings, (consisting of the spring bolts 7c, 7aoperated by the thumb pieces o, a through the medium of the connectingstraps ZJ, b), are attached to one plate in the following manner. Thumbpiece a is attached by its stem s to strap o, and thumb piece a isattached by stem s to strap o. The strap o is hinged at It in order onaccount of its length to insure steadiness of motion. The stems s and spass through suit-able openings in the plate p. The bolts 7c, 7c arekept by the force of the spiral springs projecting through and beyondthe plate p, so as to take into the no-tches o o in the upper and lowersashes. The bolts are guided by their openings through which they passin plate D and also by their stems r 1 passing through openings in thegallows frames g, g. The spring roller is shown in F ig. 4E in positionin the upper sash where n exhibits a common fiat spring at the free endof which is a friction roller m, the spring being let into a slightmortise in the sash and the roller projecting; for the purposes abovementioned.

It will now be seen clearly that while the lower sash is up or open, theupper sash may be controlled and fixed in any desired position bypressing upon the thumb piece a and seizing the sash with the hand fromabove or under and behind the lower sash.

Vhat I claim as my invention in window sash fastenings, is-

1. Arranging the spring catch fastenings for the upper and lower sashabout the middle of the frame in such manner that the upper sash can bemanaged, or fastened and unfastened without interference from the lowersash substantially in the manner herein set forth.

2. I claim the particular arrangement of the attachments on the oneplate, of the two spring fastenings, said arrangement oonsisting in theswing bar o (through which the spring bolt 7c of the upper sash isoperated), with its hinge joint in the rear of the spring bolt 7c, andthe bar o and bolt 7c of the lower sash by which I gain economy of roomand a cheap and eiiicient action upon the two sashes, in the manner setforth.
